Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed March 21, 1907. Serial No. 363,729.

To all whom it may concern:

Be, it known that I, GEORGE W. ROSENGARTEN, a citizen of the UnitedStates of America, residing in Home Heights, in the county of St. Louisand State of Missouri, have invented certain new and useful Improvementsin Water-Elevating Apparatus, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification.

My invention relates to an apparatus for elevating water from a Well bythe use of compressed air, the invention having for its object theconstruction of an apparatus of this character of efficient nature thatmay be readily controlled and one in which provision is made for thesaving of a portion of the compressed air after it has been once broughtinto use and the re-use of such saved air with the obvious gain.

Figure I is a view partly in elevation and partly in vertical section ofmy apparatus. Fig. II is ,an enlarged view partly in plan and partly inhorizontal section of the motor by which the air controlling valve ofthe apparatus is operated. Fig. III is a side elevation of the motorshown in Fig. II. Fig. IV is an enlarged vertical cross section takenthrough the motor. Fig. V is an enlarged elevation of the grooved valveactuating wheel associated with the supply valve of the motor and partsadjacent thereto. Fig. VI is a vertical cross section taken through themotor supply valve. Fig. VII is an enlarged vertical section of the airand water controlling valve. Fig. VIII is a horizontal cross sectiontaken on line VIIIVIII, Fig. VII. Fig. IX is a horizontal cross sectiontaken on line IXIX, Fig. VII. Fig. X is a similar view to Fig. IX withthe valve that controls the flow of air shown in an altered positionfrom that in which it is seen in Fig. IX.

1 designates a water receiving tank that is placed in the bottom of awell and is adapted to receive water that is permitted to enter into itfrom the well and is forced therefrom under air pressure in the mannerto be hereinafter explained.

2 is a service water conducting pipe that has an open end terminating inthe water tank preferably near the bottom thereof, and which may extendto any pointat which it may be desired to deliver water that is forcedfrom the tank through the pipe.

3 designates a valve housing through which the entrance of water intothe water tank from the well takes place and through which the flow ofcompressed air occurs in the operation of the apparatus. This housing isprovided with a tubular neck 4 that communicates with the interior ofthe water tank and which is equipped with a flap valve 5 that opensinwardly in the tank, see Figs. I and VII. The housing is also providedwith port nipples 6, 7, 8 and 9 through which compressed air enters anddeparts from the housing as will hereinafter appear.

10 is a plug valve that is seated in the valve housing 3 and is providedat its upper end with a chamber 11 that has communication with theexterior of the valve by means of ports 12 in order that water may entersaid chamber from the well in which the water tank and the valve arelocated. In the wall of the valve 10 is a port 13 that is adapted to beturned into and out of registration with the duct in the housing neck 4in order that water may flow from the well into the chamber 11 of thevalve and therefrom into the wa ter tank or such flow may be cut offwhen desired. The valve 10 is provided at its lower end with a port 14and a port 15, see Figs. VII, IX and X, that are adapted to registerwith the ports in the nipples 6, 7, 8 and 9 in the valve housing 3 aswill be described. The valve 10 has fixed to it an operating rod 16which extends to the exterior of the well in connection with which theapparatus is used and is operated for the manipulation of said valve bya motor to be hereinafter fully described.

17 designates a main compressed air reservoir in which air may beconfined under any desired degree of pressure and 18 is an auxiliarycompressed air reservoir.

19 designates an air conducting pipe leading from the main air reservoir17 and connected to the port nipple 6 of the valve housing 3, this pipebeing designed to deliver compressed air from the main reservoir to theinterior of the water tank 1 in conjunction with an air conducting pipe20 that is connected to the port nipple 7 of the valve housing 3 andwhich pipe 20 leads to the upper end of the Water tank, as seen in Fig.I. When the delivery of air from the main air reservoir to the watertank is to take place, the valve 10 is turned into the position in whichit is seen in dotted line Fig. IX, whereby the port 14 in said valvecoincides with the ports in both of the port nipples 6 and 7, while theport 15 in said valve is out of registration with any port in the valvehousing. When the compressed air from the main reservoir is admittedinto the water tank and water is present therein, said water is readilyforced under the air pressure from the water tank through the serviceconducting pipe 2, as will be readily understood.

21 designates an air conducting pipe leading from the port nipple 8 ofthe valve housing 3 to the auxiliary air reservoir 18. This pipe isdesigned at certain times during the operation of the apparatus toconduct compressed air from the water tank to the auxiliary airreservoir instead of the air being exhausted to the atmosphere from saidtank and this delivery of air from the water tank to the auxiliaryreservoir takes place when the port 14 in the valve 10 coincides withthe ports in the port nipples 7 and 8 of the valve housing 3 (as seen infull lines Fig. IX), to which the air conducting pipes 20 and 21 areconnected, the said flow of air being permissible due to the pipe 20leading from the water reservoir to the valve housing 3 and the pipe 21leading from said valve housing to the auxiliary reservoir. 22 is anexhaust pipe leading from the port nipple 9 of the valve housing 3 andextending to a point above the water level in the well in which thewater tank 1 is located. The air present in the water reservoir ispermitted to escape at certain times through said exhaust pipe and thisoccurrence takes place when the valve 10 is moved so that the port 15 insaid valve will coincide with the ports in the port nipples 7 and 9, (asseen in full lines in Fig. X) thereby permitting the flow of air fromthe water tank through the pipe 20, the du ct 15 in the valve 10 andinto the exhaust pipe 22.

It is also to be here noted that the passageway in the tubular neck 4 ofthe valve housing 3 and the port nipples '7 and 9 in said housing are solocated relative to each other and the ports 13 and 15 in the valve 1.0are so located relative to each other that when the valve 10 is moved topermit exhaust of air through the exhaust pipe 22 the port 13 willcoincide with the passageway in the tubular neck 4 and water will passthrough the valve 10 and into the water tank 1.

1 next come 'to the operating mechanism for the valve 10 that controlsthe flow of water into the water tank 1 and the flow of air through thepipes 19, 20, 21 and 22. 23 is a bed that is placed in a fixed positionpreferably adjacent to the main air reservoir 17 and is surmounted bystandards 24. 25 is a piston rod immovably mounted in the standards 24and upon the central portion of which is rigidly mounted a piston 26,preferably provided at its sides with cup leathers 27 (see Fig. 11). 28is a cylinder reciprocally mounted upon the piston rod 25 which servesas a guide for the cylinder. 29 is a horizontal valve housing supportedby the bed 23 and located adjacent to the cylinder 28. This housing isprovided with an inlet port nipple 30, branch pipe nipples 31 and anexhaust port 32. 33 is an air conducting pipe leading from the main airreservoir 17 to the inlet nipple 30 of the valve housing 29 for thepurpose of delivering air to said housing. 34 are flexible branch airconducting pipes connected to the valve housing nipples 31 and leadingto the ends of the cylinder 28. 35 is a double-ported plug valve that isseated in the valve housing 29 and is adapted to control the flow of airthrough said housing in order that the air may be delivered at theproper times to either end of the cylinder 28 and simultaneouslyexhausted from the other end of the cylinder. 36 is a grooved valveactuating wheel fixed to the stem of the plug valve 35 and which isprovided at its outer face with a stud 37 located eccentrically to theaxis of the wheel.

For the purpose of rocking the grooved wheel 36 and rotating the valve35 to which said wheel is attached, I utilize a cord or rope 38 that iswrapped around the wheel and attached thereto and at a certain point.The ends of this cord are connected to a hand lever 39 at opposite sidesof a point of pivotal support 40 for said lever. It will be seen thatwhen the lever 39 is moved in one direction the valve 35 will be rotatedin one direction in the valve housing 29 and when the hand lever ismoved in the opposite direction said valve will be rotated in adirection the opposite to that first named, with the result of causingthe air delivered to the valve housing through the conducting pipe 33from the main air reservoir 17 to be directed as required through abranch conducting pipe 34 to the proper end of the cylinder 28. When airenters the cylinder at either end it is confined between the stationarypiston 26 and the head of the cylinder at the end into which the air hasentered for pressure action against said cylinder head to carry it in adirection away from the piston, whereby the cylinder is moved upon thepiston rod 25. I

The valve 10 is caused to cooperate with the cylinder 28 through themedium of a rack 41 carried by the cylinder and a gear member 42 that isfixed to the upper end of the valve rod 16 to which said valve 10 isrigidly connected. It will therefore be seen that when any movement isimparted to the cylinder the valve 10 will be rotated in a degreecorresponding to the movement of the cylinder with the result ofcontrolling the admission of water into the water tank and the flow ofair through the valve 10 and the surrounding housing 3 and through theair conducting pipes 19, 20, 21, and 22 that are connected to said valvehousing. 28 is a stop lug carried by the cylinder 28 and adapted toengage the stud 37 carried by the grooved valve actuating wheel 36 forthe purpose of maintaining said cylinder in a stationary centralposition at certain times during the operation of the apparatus.

In the practical use of my water elevating apparatus the operations arecarried on as follows: Assuming first, with reference to the drawings,that the cylinder 28 is located at the extreme right hand upon thepiston 25. When the cylinder is moved to this position it has, throughcooperation with the valve rod 16, caused the valve 10 to be so turnedthat communication is established between the water tank through thevalve port 13 and the tubular neck 4 of the valve housing 3 in orderthat water will enter the tank. While the valve is in the positionstated, iree egress of air from the water tank is permitted through theair conducting pipe 20, the duct 15 in the valve 10 and the exhaust pipe22. Now, by manipulation of the governor valve 35 through the medium ofthe hand lever 39 and intermediate parts said governor valve is moveduntil passage of air will be permitted through the valve hous ing29vfrom the air conducting pipe 33 leading from the main reservoir whilethe valve 35 in said housing is in the position illustrated in Fig. VI.Air is thereby permitted to enter into the left hand end of the cylinder28 and said cylinder is first moved to a central position providingcommunication between the water tank 1 and the auxiliary reservoir 18,but said auxiliary reservoir being empty at this time, the forming ofthe communication between the auxiliary reservoir and water tank is ofno importance. The cylinder 28 is then permitted to move to the extremeleft hand upon its supporting piston rod with the result of causing amovement of the valve 10 in the direction indicated by the featherlessarrow, Figs. IX and X, and when the cylinder reaches the limit of itsmovement, communication is established from the main air reservoir 17with the water tank through the air conducting pipes 19 and 20, due tosaid air conducting pipes being placed in communication with each otheras a result of the port 14 in the valve 10 being in the dotted lineposition illustrated in Fi IX. Air therefore passes from the main airreservoir to the water tank and acts by pressure upon the water in saidtank to force it from the tank through the service conducting pipe 2 inwhich connection it should be here stated that the delivery of waterfrom the tank is discon tinned before the water seal at the lower orentrance end of the service conducting pipe is broken. The cylinder 28is next moved from the left hand end to a central position, due tomanipulation of the valve 35 to cause delivery of air into the righthand end of the cylinder 28, whereby the valve 10 is moved inthedirection indicated by the feathered arrow, Figs. IX and X and theport 14 in the valve 10 is caused to be placed in communication with thepipe 20 leading from the water tank and the pipe 21 leading to theauxiliary air reservoir 18. The air under pressure in the water tank istherefore permitted to flow from said tank into the auxiliary reservoiruntil the pressure in each of these members becomes equalized with theob ject in view of saving the air that is delivered into the auxiliaryreservoir for future service. As the cylinder reaches its centralposition it .is stopped and held thereat by the engagement of the stoplug 28 carried by the cylinder with the stud 37 carried by the valveactuating wheel 36. The cylinder is then released from its centralposition by disengagement of the valve actuating wheel stud from thestop lug 28 and the cylinder is permitted to move to the extreme righthand until the port 15 in the valve 10 is in the position illustrated inFig. X and communication is established between the air conducting pipe20 leading from the water tank and the exhaust pipe 22 so that the airpresent in the water tank will be exhausted to the atmosphere. While thevalve 10 is in the position just referred to, communication isestablished between the water tank and the well in which it is located,due to the port- 13 in the valve 10 coinciding with the tubular neck 4of the valve housing 3 and the tank is therefore again filled withwater, the air present in the tank and which was not delivered to theauxiliary reservoir 18 readily escaping from the tank through the pipes20 and 22. Air is next admitted through the valve casing 29 upon theactuation of the valve 35 and passes into the left hand end of thecylinder 28 with the result of causing the cylinder to be moved againtoward the left hand and to a central position with a consequence of somoving the valve 10 that the pipe 20 leading from the water tank to thevalve casing 3 and the pipe 21 leading from the valve casing 3 to theauxiliary air reservoir 18, are put into communication with each other.The air present in said auxiliary reservoir is thus permitted to pass tothe water tank and exert force upon the water therein until its pressurehas become so diminished as to be unsusceptible of water elevatingaction. The cylinder is then freed and permitted to move to the extremeleft hand, whereby the air conducting pipes 19 and 20 are again placedinto communication with each other and air is permitted to flow from themain air reservoir 17 to the water tank to continue the Water elevatingaction for a period sufiicient to deplete the supply of water in thetank. Air pressure is then again permitted to enter the cylinder 28 atits right hand end to carry the cylinder to a central position so that aportion of the air present in the water tank will flow therefrom to theauxiliary reservoir 18 for renewal of the supply therein after which thecylinder is permitted to move to the extreme right hand for the purposeof opening the passageway through the valve 10 to the water tank for'the inflow of water into the tank and the escape of air from the tankthrough the air conducting pipe 20 and the exhaust pipe 22.

The foregoing specifies all of the steps in the operation of theapparatus and these steps are carried out over and over in the mannerspecified, it being understood that the step last named is the same asthat first referred to in setting forth the operation.
